This invention relates to a temporary erection framing to be used forsupporting 'objects preparatory to assembling said objects. Erectionframing'is orten necessary in 'construction `work to'suppor't thecomponent parts of objects while they are `being assembled. One of theplaces in which suc-h erection framing `may be used is in the assemblingof floating roofs to 'be used in floating roof tanks. It hasformerlybeen the practice to erectthe shell of the tank and thenassemble 'the roof `within the shell lon framing resting on the door oftheV tank. This iramingwas formerly composed of ordinary wooden beams.Such aiprocedure'however, has the disadvantage of being expensive, asittook a lot of time to place the beams properly and then to remove themaiterxtheroof had been assembled.

In order to enable workment to build oating roofs and other structuresmore quickly and with less trouble, it was necessary that some othertype of temporary erection framing be used. The prsent framinghas `theYadvantage of being'easy to assemble, taking up very little space, andbeing readily disassembled. The new temporary erection framing is madeup of several pieces of equipment that are light in weight and notbulky. By the use of the new erection framing much time and labor can besaved, and a better job can be done. The framing can be used over andover again, and can be easily transported from one job to another. Sinceusing this temporary erection framing the jobs have been completedfaster and with less difficulty and less expense.

The new erection framing comprises individual vpieces of equipment, witheach piece comprising a pedestal; an adjustable, substantially verticalpost member to be held by said pedestal; a support for a removable basemember, such as a wooden beam; and means for locking said post member onthe pedestal to maintain the support at a desired elevation. In apreferred embodiment the pedestal comprises a substantially equilateraltriangle having sections of pipe at each apex thereof with all the pipessubstantially aligned with the center of the triangle. The pipe -membermay be held within any pipe section to extend upwardly, and the oppositeside of the triangle will then serve as the base of the pedestal. Thepipe member may be locked at a desired height by any means desired. Thetop end of the pipe member will hold an upwardly extending forked memberwith the pipe member extending through the base of the fork so that basemembers may be held within the fork on either side of the pipe member.

.72 Claims. (Cl. I.248--3540 The invention will be 'described as relatedto the embodiment set out in the accompanying drawings. Of the drawingsFig. 1`is a fragmentary plan View of the shell of the floating roof tankwith the temporary erection framing in place `for assembling a floatingroof; Fig. f2 is `a vertical section taken alon'gvline 2-2 of Fig. l;Fig. B is a vertical `section taken along line 3-3 of Fig. 2; Fig. 4 isa vertical section taken along vline 4-4 of Fig. l; Fig. 5 is a frontelevation of one of the pedestals and pipe members; Fig. 5 is a sideelevation of said pedestal and pipe member; Fig. *7 is a plan View ofsaid pedestal and pipe member; Fig. 8 is a vertical section showinguaportion ofthe shell of a floating roof tank with a stirrupattachedfthereto; and Fig. 9 is a vertical section taken along line 9--9of Fig. A8.

Eachunit of the temporary erection framing comprises a pedestal I, anupwardly extending pipe member II, and an upwardly extending `U-shapedmember I2 mounted on the top portion of the pipe member I I.

VEachpedestal i0 vhas lthe shape `of an yequilateral triangle with pipesections I3 at each apex of the triangle and with pieces of angle ironI4 connecting the pipe sections I3 to form the equilateral triangle. Allpipe sections are substantially aligned with the center of the triangleand bisect the angles formed by the sides of the triangle.

The pipe member II has an outer diameter smaller than the inner diameterof the pipe sections I3. The pipe member may be held within any pipesection I3 with the opposite side Ma of the triangle serving as the baseof the pedestal. The pipe member II may be held at any desired elevationand a nut I5 may then be welded to the pipe member II just above thetopmost pipe section I3. This nut prevents the pipe member from slidingfurther within the pipe section.

The U-shaped member I2 which serves as a fork has a hole in its bottomplate through which the pipe member Il extends with the member welded tothe U-shaped member. Wooden beams IB may be held in place on either orboth sides of the top of the pipe member II, and may be fastened bynails I1 driven through holes I8 provided in the sides of the U-shapedmember. It is preferred that the nails be not driven all the way in sothat they can be easily Withdrawn (Fig. 5). The bottom portion of theU-shaped member I2 is preferably provided with upwardly extending sharppoints I9 which may be formed by punching a hole through the base with asquare punch.

These points help anchor the wooden beams I6.

When using such temporary erection framing for erecting floating roofsthe shell 20 and bottom 2I of the tank are assembled. Stirrups 22 areWelded to the shell 20 at a desired elevation to hold the outer ends ofsubstantially radial beams I6. These stirrups have iiat bottoms 23 andupwardly extending side portions 24 and 25. One of the side portions 24is higher than the other side portion, 25. The high portion has an edgesloping toward the shell, while the other side portion 25 has an edgesloping away from the shell. The shorter side portion 25 is providedwith a hole 26, through which a nail may be driven to hold its Woodenbeam I6. Y

The pedestals I and the pipe members II are then placed at their properlocations, and the pipe members adjusted to the desired height. Aspointed out the pipe members are held at their desired elevation bywelding nuts I5 on each pipe member. The wooden beams I5 are then placedin the U-shaped members I2 and nailed in place. A typical assemblyshowing one arrangement of the temporary erection framing is shown inFig. 1. Any other arrangement may of course be used, depending upon theparticular structure to be assembled. As the pedestals IIJ aresubstantially planar and stand on edge, adjacent pedestals for any beamI6 may be turned at right angles to each other in order to give thestructure stability.

After the floating roof or other structure has been assembled thepedestals lil, pipe members II, wooden beams IIB, and stirrups '22 areremoved. As each portion of the framing is relatively small thedisassembling -of the framing is simple. The framing may then betransported to another job and used over and over again. Any apex ofeach pedestal I6 may be used to hold a pipe member I I so that if onepipe section I3 is damaged the pedestal is not ruined, but can be usedwith either of the other two pipe sections to hold the pipe member. K

Having disclosed my invention as related to one embodiment of the same,it is my intention that the invention be not limited by the details ofdescription unless otherwise specified, but rather be construed broadlywithin its spiritl `and scope as set out in the accompanying claims.

I claim:

1. Temporary erection framing comprising: a pedestal, an adjustablesubstantially vertical pipe member to be held by said pedestal, asupport for a removable beam member mounted on said pipe member, saidsupport including an upwardly-extending forked member attached to thepipe member with said pipe member extending through and beyond the baseof the forked member whereby beam members may be held within the fork oneither side of and spaced by the pipe member, and means for locking saidpipe member on the pedestal to maintain said support at a desiredelevation.

2. Temporary erection framing comprising: a pedestal having the shape ofa substantially equilateral triangle, a pipe at each apex of thetriangle, said pipes being in the plane of the triangle and beingsubstantially aligned with the center of the triangle, an adjustablesubstantially vertical pipe member insertable through any of said pipes,the side of the triangle opposite the apex at which the pipe member isinserted serving as a base for the pedestal, a, support for a removablebeam member mounted -on the pipe member and means for locking said pipemember on the pedestal to maintain saidsupport at a desired elevation. y
